Spcecntion of Letters Patent.

Be it known Hint DAVID G. NnnnsoN, o, citizen of the United Sintes. residingr it Columbus, in ine county of Franklin and Sinto of (Ehio, have invented a new und nseful Tlnpiwjweinent in Pipe-Fittings; and do hereby declare the following, when taken in connection with the accompanying drawings and the chainoi'ei's of reference marked Ithereon, io be n full, clear, and exact deseiiption of the seine, and which said drewings constitute part of this eppiieetion, and represent, in-

Fim 7 a sectional 'view of an elbow pipe-fitting embodying my invention. Fig. 8 n Corresponding View of a sieeveeoupiing embodying my inif'ention.

My invention relates to en improvement in pipe fii'iings, the object being to produce e simple, convenient and stfong pipe-tiingg adapted to assume :i vni'iet-y of forms according to the circumstances of use, and pai-ic tienlarly designed foi' use in the instnihiion of pipe-railings, and designed to :save fne time, labor sind expense attendent upon die threading of the pipe-fittings and pipe-seo tions oi' iengihs.

`Wih hese ends in View, i'nv invention oonsisis in n pipe-fitting having certain de- Coils of construction as will be heieinni'iei descfibed :ind pointed ont'in the claims.

,in carrying oni', xny invention :is shown in igs. i to C ineinsive. ine 'foin' iniegisi :wins 3, 4 and 5 of the foiii'ni'ined pipe-infine; 5 ae ouch 'inoi'idixi with n. non of opor siily ioenied ini'eg'ioi Wedges 'Zehe points of which turn oniwmd und iei'ininno vif-eli Within die onier ends oi die smid zu'nis. These foin pairs of Wedges are sjgnnineiiri'- eeiiy iomei'i so 'inni'. efni jouir o .copies die seine i'einii'e 1Qosiiifm in ne i'espeeiive nin'is of ne iiiling'. Lne bores oi ini'eiioi' chiuni-eis 3 o? iziic 'd mins i :ind 5, instead of being mede cylindrical in die ordinary way, are made tapering with their inrgei' ends inward to conform to 'the arrangement of the Wedges 7 the arge ends of which we arranged inwfigd.

With such a. fitting as above described, pipe-lengfhs or pipe-sections are used, but instead of being needed in the common Way, their inner ends are formed with oppositey located slots or ents 1.0 corresponding substantially in depih to the tapering bores 8 of the fin-inv. Now' when the pipe-secions; so slotied are driven into the respective anne 2, 3, i and 501e. the fiting 6 with their slots l0 carefully aiined with ihe poined outer. endlsof the wedges i', the ipes are orced' and 13 of which zne provided n'iih inici'F nelly arranged ontwni'diy pointed integini Wedqes 14, While the boies l5 o the minis are tapered aceodingiy with 'the-ii. onimends sineiier 'than their inner ends. Tt i# apparent tha the pipe 9 shown in Fig. may be applied "o the elbow pipediiiting l in precisely the sanne manner es Sinin-n i Fig, 4;. So, too.v the sleeve-like coupling oiiiiosie ends formed, wiii pairs of in'egiei ontnndiy pointing Wedgesv 17 Located within tapering bores 1S *die oni-ei' ends of which :we sinni'ier infin their inner en( fdioii pipes Eike the pipe ni'iy :Liso nloe 'ih-f. Coupling 1G 'in the seme wey :is iiinstinied in' Fig. if is immaterial Whether my imm-ovini pipe-fitting has one or nioije :Uinsforn'xed wih "sanering openings corr i'ziiningg' ontwmdiy pointing Weigges. it is' also apparent tiled., one oi' more Wedges may he employed within each :ii-in as desired.

i: p piied in efernbiy,however, two Wedges will be need. i

In :my oase the wedgeoi" Wedges xviii inning:-

forined npoiniie side Nelis oi" fine tapering bore or bores into winch they wiii inemiiy project. Under i'his nmengement the pipes in line with the centers of the hores. call attention' to the 'feet that eaeh wedge is supported laterally along its xnnerfedge and isf-,thus left free both at its point and bese.

f ,Each wedge is therefore 'supported along its eide instead of bese es heretofore in consanctions' in w'hiebxredgee have been used.

I chime-e I 1. Asi a.l new* article of manufacture, n ppe-ttmg; having en erm formed with e.

, tapered bore and provie with en. eutwerly pointing wedge ext/ending. laterally inward Ainto the said bore from the sidewell thereof and supported from end'to venl along' its weint and. base, whereby a slotted pipe innneredge by Jche seid wal and lfree at its v serted into 'fche bore wil be expande by the wedge and thus fastened to the fitting.

2; As a new article of manufacture, a ppe-tting having an erm formed with a. tapered bore, and a plurality-of opposey located outwardly pointing wedges exten ing ,laterally inward from the side walls of the said bore, whereby a slotted pipe inserted into the bore wil be expanded by the wedges :md thus fastened to the ting.

In'testimony whereof, I have sgned this speceaton yin the presence/of two subscribing r.',vnnesse's.
